Example 3: Simplest Case - with a Priority Resource

IMPORTANT NOTE!

In vidigi 0.0.5, the original implementation of VidigiPriorityStore was rewritten, with the version available in 0.0.4 renamed VidigiPriorityStoreLegacy.

If upgrading, you can change your import statement from

from vidigi.utils import VidigiPriorityStore

to

from vidigi.resources import VidigiPriorityStoreLegacy as VidigiPriorityStore

to allow your code to continue working in 0.0.5 with no other modifications.

The 0.0.5+ version of VidigiPriorityStore is designed to simplify the incorporation of vidigi into models that use simpy resources, minimizing the syntax changes required when requesting a resource. Take a look at example_7_simplest_case_priority_resource_storewrapper.ex_7_model_classes.py for an example of its use.

Generate animation using the step-by-step functions

Using the three step-by-step functions allows us to intervene in the produced dataframe and manually take control of the icons in use.

This will allow us to show the high-priority patients with a unique icon so we can see their frequency and how they are handled in the final model.
